Immutable Infrastructure

28. @bglpe
Immutable
Infrastructure
Myth

29. @bglpe
“The least-cost way to ensure that the behavior of any
two hosts will remain completely identical is always to
implement the same changes in the same order on both
hosts.”
Order Matters

30. @bglpe
Management Methods
• Divergence
• Convergence
• Congruence

31. @bglpe
Why (When) Does Order
Matter?
• Circular Dependancies
• Right Command Wrong Order
• Right Package Wrong Order

32. @bglpe
Package Example

33. @bglpe
Immutable Infrastructure
“Model”
• No CRUD allowed for…
• Packages
• Configuration Files
• Application Software
• Data (RUD)

34. @bglpe
How To Do Immutable?
• Provision a new server.
• Test the new server.
• Change the reference to the new server.
• Keep the old server around for rollback.

35. @bglpe
The Immutable “Trombone”
• Golden Images
• Virtual Desktop Infrastructure (VDI)
• Virtual Images
• Phoenix Servers vs Snowflake Servers
• Infrastructure as Code
• Bake vs Fry
• Containers

36. Immutable Delivery

37. Immutable Delivery

39. V4L Principles
• Variety
• Determine your variety of offerings
based on operational efficiency and
market demand
• Velocity
• Maintain a steady flow through all
processes of the supply chain
• Variability
• Manage inconsistencies carefully to
reduce cost and improve quality
• Visibility
• Ensure the transparency of all
processes to enable continuous
learning and improvement

40. Left to Right Flow
•Variety
• Lean Startup
• Minimal Viable Product
• Pivot
• Build Measure Learn
• Customer Development
Methodology

41. Left to Right Flow
• Velocity
• Developer Flow
• Integration Flow
• Deployment Flow
https://upload.wikimedia.org/wikipedia/commons/7/74/Continuous_Delivery_process_diagram.png

42. Left to Right Flow
• Variation
• Converged Isolation
• Immutable Infrastructure
• Immutable Delivery
https://en.wikipedia.org/wiki/Standard_deviation

43. Left to Right Flow
• Visibility
• Containerization
• Microservices
• Data Gravity

44. @bglpe
Visibility
• Where and when was it built and why
• What was its ancestor images
• How do I start, validate, monitor and update it
• What git repo is being built, what hash of that git repo was built
• What are all the tags this specific container is known as at time
of build
• What’s the project name this belongs to
• Have the ability to have arbitrary user supplied rich metadata
